I took the SJ4000 outside for a quick swing n dig to see how it would work for making metal detecting hunt videos. While the picture was pretty good the sound wasn’t very good. I used the slit backing on the waterproof case. I chest mounted the camera so I could see the screen. There wasn’t just one position that worked for swinging and digging, so adjustment was required.
There was way too much vibration while digging. I really need to head mount the camera, and that means I need to upgrade to a wifi camera so I can see the framing on my iPhone.
